ABS System Self-Diagnostics

The Bendix Antilock-10 Brake System is monitored by the Controller - Antilock Brake (CAB). The CAB monitors critical input and output circuits within the antilock brake system of the vehicle, making sure they are operating correctly.

Some circuits are tested continuously; others are checked only under certain circumstances.

Each circuit monitored by the CAB has a corresponding fault message assigned to it. Refer to "ABS System Fault Messages" for a list and definition of the fault messages.

- If the on-board diagnostic system senses that one of the circuits is malfunctioning, it stores the corresponding fault message in memory.

- If the malfunction goes away after the fault is stored, the fault message will be erased after 50 key cycles (with the exception of the CAB fault).
